OpenCut Interface

🆕 What's New in v0.4.0

This release rebases the embedded OpenCut onto upstream main after ~8 months of heavy development (≈364 commits since the v0.3.0 build on 2025-08-30). The highlights below are from the OpenCut project itself — they apply to the editor running inside this plugin as well.

Rendering engine — WebGL ➜ Rust/WASM GPU renderer

• New GPU renderer migrated from WebGL to wgpu compiled to WASM (with a WebGL fallback while WebGPU support stabilizes in browsers).
• Time, effects, and mask logic split into dedicated Rust crates (opencut-wasm) — shared between web and the new desktop build.
• Batched GPU command encoding, degraded-renderer banner, and graceful handling when no GPU is available.

Keyframes & animation

• Rewritten animation system using scalar-channel bindings.
• Graph editor for flat keyframe segments — a new popover lets you edit multiple properties at once.
• Expandable keyframe lanes directly in the timeline.
• Keyframes now wired for opacity, text color, every background property, and per-axis position animation.
• Clipboard-level keyframe paste.

Effects & masks

• New WebGL effects system — starts with a Blur effect and per-clip effect stacking with asset sorting.
• Cinematic bars, diamond, heart, star, and custom/text masks, with stable background-blur previews.

Timeline & editor UX

• Move/resize/split/delete multiple elements at once.
• Clip volume line visualized directly in the timeline.
• Waveform rendering improvements and correct audio waveform height.
• Timeline auto-scroll while dragging clips.
• Copy/paste for elements; ripple support for element resize.
• Select-on-insert; centralized selection management.
• New preview overlay system (guides, bookmark notes).

App surface

• Desktop app scaffolding (Tauri) introduced.
• Changelog page with markdown + technical-detail support; "new release" notice.
• Branding page; mobile-gate screen; history view in the feedback popover.
• Audio separated from elements (export now handles audio consistently).
• Migration system rewritten (run() + pure v1→v2 transforms) with new storage-schema migrations.

Under the hood

• File tree restructured into domain modules (editor/, timeline/, preview/, project/, media/, etc.) with a cleaner dependency graph.
• Time utilities migrated from TypeScript to Rust WASM.
• Unified element-update pipeline and centralized ripple handling.

Plugin-side fixes in this build

• All assets and routes honor the /opencut basePath (logo, landing image, country flags, effect previews, PWA manifest).
• RSC prefetch URLs served by the Python handler now cover Next.js 16's dot-separated __next.<seg>.__PAGE__.txt format.
• getEditorUrl / getProjectsUrl no longer double-prefix basePath when passed to <Link>.
• Sounds-search and other removed server routes are gracefully skipped in ComfyUI mode.
• Save timer no longer throws after closing a project.

See docs/COMFYUI_INTEGRATION.md and docs/COMFYUI_BUILD_CHECKLIST.md in the OpenCut repo for adaptation details and future rebase guidance.
